Heavy metals are an urgent environmental problem, since their high concentrations have a negative impact on soil chemistry. Solid domestic waste landfills are a direct source of heavy metals accumulation in soils. Landfills pollute and poison large areas around them. Heavy metals are concentrated in the surface layer of the soil 0–10 cm deep, and can later migrate into plants and further into living organisms. The article examines soil pollution by the total content of heavy metals (Pb, Cd, Cu, Zn, Ni, Co, Mn) in the areas adjacent to Tbilisi and Telavi (Georgia) landfills and on illegal landfill in the village of Anaga (Sighnaghi municipality). The results show that the soil cover of the territories adjacent to solid domestic waste landfills and illegal landfills is contaminated with heavy metals. The data obtained confirm the migration of heavy metals mainly in terms of the distance from the landfills. High concentrations of heavy metals in soils are characteristic of lead and cadmium. There is also a tendency towards a decrease in the content of lead, cadmium, copper, zinc with distance from the landfill of solid domestic waste.

During the conducted study, 18 objects of illegal dumping of waste were inventoried. All inventoried objects are located in the north-west part of the Barlinek municipality. Each found illegal landfill was measured with measuring tape and its length, width and height of the deposited waste was recorded. For each location, percentage content of waste deposited, as well as its surface area and volume were calculated. All located waste landfills were divided into spot waste landfills, multi-point landfills, area landfills and linear landfills. Spot landfill is the dominant type of illegal waste landfills - 12 objects, multi-point landfills were found in three locations and area landfills in two locations. Only one linear landfill was located. Waste disposal sites were located at different distance from residential areas. It has been determined, that the formation of illegal waste landfills is very often linked to the ease of availability of the local residents to the locations of waste disposal in the form of access roads or good location of the site. It has been determined, that despite the reforms of the waste management, abandonment of waste on undesignated sites is still observed - at six places the new wastes has been added after the 4 years from first observation and only 2 places were cleared.
